, GRASS Box Eon LAWN MOWERS Charles Francis Booton, Anstey, England, assignor to The J. P. Engineering Company Lim- -ited, Leicester, England Application May,30, 1945,; Serial No. 596,790 In Great Britain June 24, 1944 This invention is for an improved grass-box ,for lawnmowers. As is well known in the construction prevailing in this country the grass-box of a lawnmower consists of a short trough which, when the box is mounted in position on the lawnmower, has its open mouth presented rearwardly in a vertical plane or in a-plane at a small angle to the vertical. Such boxes hitherto have been essentially rigid, and commonly the box consists of two metal or wooden sides or ends and a bent sheet of metal or wood (such for example as plywood) attached to and extending between said ends. It will therefore be appreciated that such a box, when packed for transport, occupies considerable space and if it is not to be scratched or damaged needs a substantial packing case to accommodate it. The present invention has for the object the provision of a grass-box which by reason of its construction occupies less space for transport and does not necessitate a bulky container, and which may be folded up into a small space for the convenience of the user when. it is not required.

According to this invention a folding grass-box for a lawnmower is of trough-like form when erected, and has the top and bottom walls of the box hinged to fold towards one another, and the end walls hinged to fold inwards. Preferably but not necessarily the end walls are hinged at an intermediate level in their height, while in order to secure the parts in their erected position there are releasable fastenings between the end walls and the top wall.

These. and other features of the invention set out in the appended claims, are incorporated in the grass-box shown in the accompanying drawings in which Figure 1 is a perspective view of the erected grass-box and Figure 2 is a perspective view showing the grass-box folded.

It will be seen from Fig. 1 that the grass-box is of trough-like form (the mouth of the trough being presented towardsthe left). The base 19, preferably of metal, curves up at the back for a short distance and at H is hinged, by a pianotype or other hinge, to the top wall l2 that curves upwards and forwards to the mouth. The end walls are indicated generally at l3 and may be of wood, such as plywood, or a plastic (as may also the top and bottom walls). They are arranged in part to fold inwards. As shown, they consist of upper and lower parts I 3a, l3b, respectively hinged together by hinges l5 so that 5 Claims. (Cl. 56199 Y the line H, thelower parts l3b being rigidlyfixed to the base l0.

shown, there are clamped members It pivoted to the end walls at H and having screw-threaded necks [8 adapted to enter slots IS in the front margin of the top wall and to receive clamping nuts 20.

When the fastenings have been released, by

The base Ill may have a lip ID at the outside of the end walls and the top wall [2 may have a like lip l2.

Any suitable means is provided for the detachable connection of the box to the lawnmower, and the lugs 2| are shown as examples suitable for one-construction of lawnmower.

I claim:

1. A lawnmower grassbox comprising in combination, a stationary bottom wall having two side edges and one transversal edge extending between the same; two stationary upwardly extending side walls along said side edges of said stationary bottom wall and each having a top edge; one stationary upwardly extending transversal wall along said transversal edge of said stationary bottom wall and having a transversal top edge; two turnable side wall members each hinged to the top edge of one of said stationary side walls and foldable towards each other; and one turnable transversal wall member hinged to the transversal top edge of said stationary transversal wall and extending in upwardly turned position to enclose a portion of said grassbox.

2. A lawnmower grassbox comprising in combination, a stationary bottom wall having a back portion curved upwardly for a short distance, said stationary bottom wall having two side edges and having one transversal edge limiting said back portion; two stationary upwardly extending side walls along said side edges of said stationary bottom wall and each having a top edge; two turnable side wall members, each hinged to the top edge of one of said stationary side walls and foldable towards each other; and one turnable transversal wall member hinged to the transversal edge of said back-portion and extending in upwardly turned position to enclose a portion of the upper part of each wall folds inwards along said grassbox.

3. A lawnmower grassbox comprising in combination, a stationary bottom wall having a back portion curved upwardly for a short distance; said stationary bottom wall having two side edges and having one transversal edge limiting said back portion; two stationary upwardly extending side walls along said side edges of said stationary bottom wall and each having a top edge, said top edges of said stationary side walls and said transversal edge limiting said back portion being arranged in one horizontal plane; two turnable side wall members, each hinged to the top edge of one of said stationary side walls and-foldable towards each other; and one turnable transversal wall member hinged to the transversal edge of said back portion and extending in upwardly turned position to enclose a portion of said grassbox.

4. A lawnmower grassbox comprising in combination, a stationary bottom wall having a back portion curved upwardly for a short distance,

said stationary bottom wall having two side edges and having one trans'versal edge limiting said back portion; two stationary upwardly extending side walls along said side edges of said stationary bottom wall and each having a top edge; two turnable fiat side wall members, each hinged to the top edge of one of said stationary side walls and foldable towards each other; and one turnable curved transversal wall member hinged to the transversal edge of said back portion and extending in upwardly turned position to enclose a portion of said grassbox.

5. A lawnmower grassbox comprising in com bination, a stationary bottom wall having a back portion curved upwardly for a short distance, said stationary bottom wall having two side edges and having one transversal edge limiting said back portion; two stationary upwardly extending side walls along said side edges of said stationary bottom wall and each having a top edge; two turnable side wall members, each hinged to the top edge of one of said stationary side walls and foldable towards each other; one turnable transversal wall member hinged to the transversal edge of said back portion and extending in upwardly turned position to enclose a portion or said grassbox; and releasable fastenings arranged between said turnable side wall members and said turnable transversal wall member.
